PURPOSE:To provide a time data receiver capable of avoiding that a large error is undesirbly included in the present time data due to the incidental duplication of unavailability in the correction of the present time data in a time counter circuit when it is in an non-receivable circumstance at a wave reception timing. CONSTITUTION:The time data receiver is so constituted as to be controlled with a CPU1, one hour is set in the reception interval memory TM of RAM 9, a time code TC is received at every one hour and exact present time is obtained to correct the present time data of a time counter circuit 7. If wave reception is unavailable, 10 minutes is set in the reception interval memory TM, rereception at every 10 minutes is tried and the present time data in the time counter circuit 7 is corrected as early as possible. |
